As airlines keep cramming in additional seats to bring in more money, passengers will not only be squeezed in the smaller spaces. Additional dollars from their wallets will be squeezed out.

Ryan Air now limits carry-ons to smaller, soft bags and backpacks that fit under seats. If you plan to fly Ryan Air and other airlines with the same restrictions, always be sure of the latest bag requirements. If you don’t want to pay the ever-growing fees for checking luggage, scan the ads for those you are permitted to carry aboard free.
